r LADDER PLATFORM.

' Application filed m 30, 1924. Serial- No. 729,178.

" provide a platform which can be removably connected to an ordinaryladder and which will not only functionasa support for articles but willalso act as a guide or holding meansto prevent lateral displacement ofthe ladder and thereby prevent accidents.

A further object is to provide a platform of this character which willsecurely hold a ladder in position against the angle or corner of abuilding and which leaves ample space for access to the corner of thebuilding either in the positioning of the drain spout, or in thepainting of the corner, or any other purpose desired.

A further object is to provide a platform of this character which whensecuredin position results in the provision of a relatively wide step onwhich the workman or operator may comfortably stand during theperformance of his work.

A further object is to construct a platform of this character whidh canbe manufactured and sold at a reasonably low price and which will mostefiiciently perform the functions for which it is intended.

With these and other objects in view, the invention consists of certainnovel features of construction and combinations and arrangements ofparts which will be more fully hereinafter described and pointed out inthe claim.

In the accompanying drawings- Figure 1 is aperspective view,illustrating a ladder equipped with one form of my improved platform andsupported at the corner or angle of a building;

Figure 2 is a view in transverse section through the platform, the viewbeing taken on the line 2-2 of Figure 1;

Figure 3 is an enlarged inverted plan view of the platform; 1 V I Figure4 is an enlargedfragmentary view in section on the line it-4 of Figure1;

Figure 5 is a perspective viewillustrating a modified form of platform;

Figure 6 is a view in section on the. line 66 of Figure 5. a

1 represents a ladder of ordinary "construction having ordinary rungs 2.3 represents a building, at the corner of whichthe ordinary drain-spout4 is shown. A represents my improvedplatform which, as il lustratedinFigures 1, 2, 3 andi, comprises a frame 5, preferably ofangular form,supporting a metal plate 6,. the latter havinga-n extension 7 whichprojects between i the parallel members of the ladder. The'frame 5'isalso provided with'lugs 8 which are positioned parallel to the sidefmembers'of the ladder and serve to hold'an' extension ladder againstlateral movement when the latter issecured against the sides of theladder 1. This platform A.may be provided with suitable extensions 9which may be composed of canvas or other flexible material mounted uponwire frames 10 and these wire frames may be caught under hooks 11 onframe 5 so as to hold the extensions in place.

The platform A is cut out so as to provide a pair of bearing walls 12,12 at a right angle to each other to engage the sides of the building atthe angle and to hold the ladder against lateral movement. These wallsare preferably reinforced by turning back or seaming the edges of themetal as shown at 13, and back of these walls the plate is recessed asshown at 1 1 so as to provide a relatively large opening sufiicient toexpose the angle of the wall to accommodate the drain pipe 4 and provideample space for v the movement of the hands or paint brush through saidopening to enable the workman to carry out his plan of operation.

To secure the platform to the ladder I provide the frame 5 with a pairof hook bolts 15, the hook ends 16 thereof engaging the upper rung 2 ofthe ladder, and the screw-threaded ends of said bolts receiving nuts 17to clamp the frame against parallel or upright members of the ladder asshown most clearly in Figure 2. I

As an additional support for the platform I provide a braceframe 18-which may be composed of Wire or suitable material .connected to eyes 19on frame 5 and at their free ends are bent as indicated most clearly inFigure 4;. By reference to this figure it will be noticed that the endsof the side members or Wires of the b13 8 m fi 3 16 bent,

providing parallel eyes 20 in which parallelrods 21 are held, andbetween the eyes 20 the Wires are curved or bent as shown at 22 so as torest upon the rung 2 of the ladder. The rods 21 are of a lengthsuflicient to position their ends againstthe parallel upright members ofthe ladder with one of these rod-s at the front of the ladder and theother at the rear of the ladder and the bent portions 22 resting uponthe rung. These rods not only. serve as a support for the platform butin co-operation with the rung they provide a relatively Wide step onWhich the operator can comfortably stand during his Work.

In the modification illustrated in Figures 5 and 61 show a platform 13Which is connected to the upper rung 2 of the ladder by hook bolts 15 asin the preferred form but I dispense with the brace frame 18 and provide:lugs 23 fixed to the platform and engagingagainstithe rear face of theladder so that When the hook bolts are drawntight the platform Will besecurely held.

Furthermore, in this modification I show the platform as having anotched bar 26 at its free edge so that this bar Will enable theplatform to rest against a glass frame and the notches will receive theribs or frame- Work therein and prevent pressure against theframeworkand also prevent lateral movement of the ladder.

While I have illustrated two forms of my invention 1 would have itunderstood that I do not limit'm'yself to them as various slight changesand alterations might be made in the general form of the parts describedWithout departing from my invention, and hence I do not limit myself'tothe precise details set forth but consider myself at liberty to makesuch slightchanges and alterations as fairly fall Within the spirit andscope of the appended claim.

I claim:

A ladder platform, comprising a plate, a bar fixed .to the plate andhaving one face at an acute angle to the plate and adapted to restagainstthe uprights of the ladder, hook bolts projecting through the barand having their hooked ends engaging a rung of the ladder, nuts on saidbolts located against the bar and clamping the bar against the ladderand securing the platform at an angle to the ladder, and an extension onsaid plate projecting between the uprights of the ladder and coweringthe rung and the hooks connected thereto.

JOHN WIRTH.
